|
|
a small cell weighs very little and is more able than a large cell to conserve energy.
|
|
|
a small cell takes up less room than a large cell.
|
|
|
a small cell has a small volume relative to surface area, increasing its efficiency of obtaining nutrients.

|
|
a small cell has a small surface area relative to volume, increasing its access to nutrients.

Detailed explanation-1: -Smaller single-celled organisms have a high surface area to volume ratio, which allows them to rely on oxygen and material diffusing into the cell (and wastes diffusing out) in order to survive. The higher the surface area to volume ratio they have, the more effective this process can be.
Detailed explanation-2: -Small cell base stations provide higher capacity than macro cells because of the deployment scenario. Because these base stations are mounted low above ground, they are less susceptible to interference. This translates directly into higher capacity.
Detailed explanation-3: -Cells are so small because they are easier to replace, and a cell needs to be small to be able to perform the tasks a cell needs to do. If cells were bigger it would be harder for the body to replace the cell without disrupting what is going on in the body and delaying a process.
